Class imbalance classification is a demanding research problem in the context of machine learning and its applications, as most of the real-life datasets are often imbalanced in nature. Existing learning algorithms maximise the classification accuracy by correctly classifying the majority class, but...

In bacterial DNA, there are specific sequences of nucleotides called promoters that can bind to the RNA polymerase. Sigma70 ([Formula: see text]) is one of the most important promoter sequences due to its presence in most of the DNA regulatory functions. In this paper, we identify the most effective...

Class imbalance classification has become a dominant problem in supervised learning. The bias of majority class instances dominates in quantity over minority class instances in imbalanced datasets, which produce the suboptimal classification results for classifying the minority class instances. In t...

Sigma promoter sequences in bacterial genomes are important due to their role in transcription initiation. Sigma 70 is one of the most important and crucial sigma factors. In this paper, we address the problem of identification of σ70 promoter sequences in bacterial genome. We propose iPromoter-FSEn...

In genetic evolution, meiotic recombination plays an important role. Recombination introduces genetic variations and is a vital source of biodiversity and appears as a driving force in evolutionary development. Local regions of chromosomes where recombination events tend to be concentrated are known...

Controlling the near field optical binding force is an emerging new area of optical manipulation. So far, there is no generic way to reverse the near field optical binding force for plasmonic or dielectric nano-dimers of distinct shapes (cube, cylinder, ring, sphere); and specially for homodimers. I...

Abstract Separating distinct nanoparticles from a cluster by applying simple nonstructured light can be a novel approach for future industrial development. Understanding the type of distinct particles from a three‐particle cluster (i.e., chiral, plasmonic, and dielectric) based on different near‐fie...
